I have been going to Nhu Lan for a few years now. This is the best place (that I've found so far) to get Bahn Mi (Vietnamese Sandwiches) in Las Vegas. It's much better than the Vietnamese to-go place across the street, and WAY larger/better than the overrated Hue Thai. Located across the street from Ichiza, Nhu Lan was remodeled within the past year to give it a more restaurant-y feel. Their bahn mi is $2.50, which seems to me about a buck too much by LA or SF standards, but it seems to be the going rate here in Las Vegas. They also have pho, rice dishes, soups, noodles, rice porridge, and a bunch of yummy Vietnamese drinks. This is my go-to place when I'm craving Vietnamese, as I haven't yet found any place better!
